Potential blood donors have to meet certain requirements to be eligible to donate. Most of the time, a donor has to weigh more than 110 pounds, be 17 years old or more and be in good overall health. These guidelines have nothing to do with the quality of the blood, but rather the health of the donor.

From there, the quality of the blood must meet further requirements.
